Make c-s to print stacktrace of all threads when it is getting forcefully killed, say getting SIGKILL and SIGABRT.

[dkropachev]

We have couple of cases when c-s stucks not generating any traffic and even not terminating in time.
To investigate it furthere we need to have ability to see what threads are doing.

[kbr-scylla]

Yes please!
we have multiple tests where c-s is hanging
here's another one: scylladb/scylladb#16219

I've created a PR, but I cannot add reviewers there. @dkropachev please check if it solves this issue.
Unfortunately I think there's nothing on application level that we can do about SIGKILL.

Not a problem any signal would be enough.

This should be opened in the correct repository for cassandra-stress --> https://github.com/scylladb/cassandra-stress.
Moving.
